This could be because you do not have a default instance of SQL Server in your machine.

Please refer to SQL Server 2005 Books online: http://msdn2.microsoft.com/en-us/library/ms137789.aspx

As it states, the default configuration file is for default instance of SQL Server in the machine. If you do not have a default instance in your machine and you want to use a named instance, then you have to modify the configuration file as described.

Please try it out and let us know if still have problems browsing the objects.|||

Thanks for the Reply ..

Thanks a lot
